Alexander Skarsgard and Ellen Page have been traveling together to promote their thriller, "The East" - and based on a newly released photo, it seems they're more than just co-stars.

"This reminds me of shooting. When we'd lie in the grass listening to [actor] Toby [Kebbell] practice Rostam's piano piece," tweeted the film's director, Zal Batmanglij, along with a photo of Page, 26, lying in the lap of Skarsgard, 36, who appears to be kissing her forehead.

Page retweeted the post, and added, "Canadian tuxedo party," a nod to the fact that in the shot, she and the "True Blood" star are both wearing denim.

The two were first spotted out together last summer, when they attended the Stanley Cup final in Los Angeles together.
